Using the iPad baseband is not the best solution to unlock iPhone 3G/3GS but if you decide to go ahead after understanding the risks, you can download it without the need of having an internet connection (although you still need to download the iPad 3.2.2 firmware). This will also help if you are stuck on the Fetching iPad baseband screen for too long. Don’t like this unlocking method? Consider this.
Using this method, redsn0w will only take about 5 seconds to download it instead of the usual 3-4 minutes. If you have a slow internet connection, it will take even longer. Note: The instructions below is for PC. I’ll post a Mac version soon.
1. Download the following files:
2. Install Appserv. Follow on screen instructions. At one point, it will ask for name, enter any name you wish then create a password. After Installation you will see a new directory AppServ is created on your C drive.
3. Open C:\AppServ\www and create a folder name iPad.
4. Create another folder inside the iPad folder and name the folder as “061-8801.20100811.CvfR5” without the ” “.
5. Copy the iPad 3.2.2. IPSW into the 061-8801.20100811.CvfR5 folder.
5. Edit the host file in C:\WINDOWS\system32\drivers\etc. Note:
- Windows 7 or Vista: Right click on Notepad and select Run as administrator, then open the host file.
- Windows XP: edit the host file directly.
6. Copy and paste the following at the end of the line of the host file and hit save.
127.0.0.1 appldnld.apple.com
74.208.10.249 gs.apple.com
Now when you run redsn0w and selecting the Install iPad Baseband option, you will notice that it will take only 5 seconds (or less) for redsn0w to download it.
Reason: This setup tricks redsnow by fetching the baseband directly on your localhost (your computer) through the help of Appserv program.
This page has detailed steps with screenshots.
Thank you level5team for the tips.

Would this technique allow you to downgrade the iPhone baseband too? Could there be a solution available through this method to downgrade the iPhone 4?
This stuff is driving me nuts
I can’t use rebel/gevey in the Netherlands…
cheers for the post!
thanks a lot!
hey iam having the proxy adress how to set… pls help me….
hey its not working…….
not enough details
It is not working. I followed everything and during redsn0w, the screen disappears after "fetching ipad bsaeband". what should i do?
then what happens?
Hi .. ok so this is whats happening with me ..
i have a 3G iphone frimware 4.2.1 Carrier Locked .. to unlock it i need to jailbreak .. i'm using redsn0w and i put the check next to install iPad baseband. after that it tells me fetching iPad baseband .. 2 minutes redsn0w disappears .. i tried it more than 7 times and the same result .. when i tried appserv i did all the steps it tells me iPad baseband fetching error ..
So What do i do now ?
with redsn0w, try avoid checking install Cydia and iPad baseband at the same time, it's a bug in the program. Either install Cydia or iPad baseband first.
Thank you .. Works as good as new ^.^ .. Wonder y these bugs aren't known .. i thought something was seriously wrong ..
Thanks a lot! That little trick worked great!
This did not work for me i still got the iPad Base band fetching error
you won't need redsn0w anymore once you have 6.15.00
thanks a lot!
I have 3Gs phone with frimware 4.3.3 with base band 05.16.02. Am trying to jailbreak through the dev team redsnow method but the iphone restore software is getting downloaded as zip file and not as .ipsw extension. When i unzip the file it still does not show .ipsw extension, there are many files there but not one file as mentioned here. plz help me.
just rename from .zip to .IPSW
download it with mozzilla instead and it downloads the ipsw not the zip automatically.
Where are the Mac instructions?
Soon!
Okay I have an iPhone 3GS that has already had base band 6.15.00 on it and has unlocked fine every time up till now. I ended up installing a bad cracked app from Cydia and having to restore. So I go to restore and it has only gone all the way through once out of over thirty times, so I have been checking everything so i went back and tried to reinstall the base band and i keep getting the fetching error. any assistance with this is much appreciated i have a custom 4.3.3 IPSW from Sn0wbreeze
if you already have 6.15.00, just use a custom firmware to restore it, you won't need redsn0w anymore
I just upgraded to baseband 6.15 and was waiting for it to finish. My iphone is now stuck in the reboot mode where only the Apple icon is showing on my phone and it is not booting up. Been waitng over 5 minutes now and still stuck with that Apple icon on the phone. Any help would be appreciated.
try one more time with custom firmware
hi guys, i seem to have the same prob w/ kevin, that is, iphone is stuck with the apple logo; i got a successful fetching of ipad baseband (i UN-checked install cydia in redsn0w), notified on my pc that apple driver support was successfully installed and saw on the phone some DOS-like program running until it stopped with the apple logo (30mins gone already);
Q: was that the reboot expected or am i stuck in the reboot process?
Q: is it safe to run cydia install in redsn0w though am not sure if the ipad baseband was successfully installed at first?
help is greatly appreciated.. .thanks guys
when the baseband is being flashed you will see this on the screen: http://www.askiphonequestion.com/how-to-update-ip…
What is the resolution to the baseband fetching error? It says to check my internet connection
it can be your internet connection is blocking access to the server… try with another computer at a different location
Been trying to upgrade the baseband of my Iphone 3g to 6.15 for the nth time now, still no luck even with this trick.
Now, I will try to use redsnow Cydia first, then Install baseband option as mentioned above. Hope it will do the trick this time.
One more question, Do i follow the same redsnow jailbreak procedure but this time select only “install ipad baseband? I mean I will enter to DFU mode again just like installing Cydia? thanks
Yes
Still no luck here… same error “cannot fetch baseband”
What version of redsnow that makes it work for you guys? thanks
0.9.6rc18 should do the trick, also check your internet connection, maybe try at a different location, it seems redsn0w is not able to connect to the bb server
done trying from office to my home internet still the same error… ok i’ll try version 0.9.6rc18 this time.
good luck
When running the .exe, i'm having 16 bit MS-DOS Subsystem saying: <path of the application> The NTVDM CPU has encountered an illegal instruction. CS:0e00 IP:0115 OP:63 63 65 73 73 Choose 'Close' to terminate the application.
dunno why, but the Appserv i dld from this site doesn't work (it's only 8Mb). I've dld from another site, and it worked (the app is approx 16Mb)
Then later on, you have to modify a the host file as described. I don't know why, but my file was named hosts instead: i removed the "s" in the name, followed this site procedure… and it worked.
Hope this can help others that will encounter the same problem.
great tip, thanks so much!
can u post the link to that site, im having the same issue, thanks
